DocumentDB (Single Host)

Learn how to add a DocumentDB (single host) database as a resource in StrongDM.

Overview

This guide outlines the configuration steps for adding a DocumentDB (single host) database as a resource in StrongDM.

When the resource is added, StrongDM proxies client connections through a node (gateway, relay, or proxy cluster). This enables centralized access control, credential management, and audit logging. StrongDM supports Amazon DocumentDB (single host) with IAM-based authentication, allowing you to connect without embedding static credentials.

Use this guide to complete all necessary preparations to add this resource to your StrongDM environment; input the correct properties in the Admin UI, CLI, SDKs, or Terraform provider; and test for a successful connection. When done, you will be able to use the StrongDM Desktop application or CLI to connect.

For general information about how to add a database as a resource in StrongDM, see our main guide, Add a Datasource.

Supported Versions and Clients

StrongDM supports Amazon DocumentDB (single host) clusters that use username/password authentication with TLS enabled. Both production and development environments are supported, as long as the cluster endpoint is reachable by your StrongDM nodes.

StrongDM is compatible with any MongoDB-compatible client or driver that can connect to Amazon DocumentDB. Commonly used clients include:

• CLI tools such as mongosh (MongoDB Shell)

• GUI clients like MongoDB Compass or DBeaver

• Application drivers for Node.js, Python (pymongo), Java, Go, .NET, and others that support the MongoDB wire protocol

Limitations

• The DocumentDB (single host) resource type supports username/password authentication only. It does not support IAM authentication. The separate DocumentDB (single host IAM) resource type is also available.

• DocumentDB requires TLS to connect.

• DocumentDB does not support connection using service (SRV) records.

• AWS Directory Service integration is not supported.

Prerequisites

To add your resource in StrongDM, you need to meet several technical and configuration prerequisites. Please ensure that the following requirements are met.

In StrongDM, you must have the following:

• Administrator permission level

• At least one operational StrongDM node (gateway, relay, or proxy cluster) that can reach the DocumentDB endpoint

• If using secrets management tools for storing your database credentials, a Secret Store configured in StrongDM

To verify that the resource is accessible by the node, log in to the gateway or relay and use Netcat: nc -zv <HOSTNAME> <PORT> (in this example, nc -zv testdb-01.fancy.org 3306). If your gateway server can connect to this hostname, proceed.

Netcat is a tool for checking various hostnames and ports by either sending data (a ping) or checking for listeners on the ports. The command in the aforementioned example use "-z" to check for listeners without sending data and "-v" to show verbose output. If you don't have Netcat, you can install the Netcat package with whatever package manager you are using, such as "apt-get install netcat".

On the DocumentDB side, you must have the following:

• Properly configured DocumentDB (single host) cluster with username/password authentication

• TLS enabled on the DocumentDB instance

• Network configuration (VPC, security groups, firewalls) that allows StrongDM nodes to connect

Resource Management in StrongDM

After all prerequisites and prep work is done, you are ready to add the resource to StrongDM. This section provides instructions for adding the resource in either the StrongDM Admin UI, CLI, Terraform provider, or SDKs.

Admin UI

Configuration Properties

The following configuration properties are required to define a DocumentDB (single host) datasource in StrongDM. These settings control how StrongDM connects to the database, authenticates the connection, and optionally uses encryption or secret management. Each property must be correctly configured to ensure connectivity and access enforcement through StrongDM.

Property	Requirement	Description
Display Name	Required	Meaningful name to display the resource throughout StrongDM; exclude special characters like quotes (") or angle brackets (< or >)
Datasource Type	Required	DocumentDB (single host)
Proxy Cluster	Required	Defaults to "None (use gateways)"; if using proxy clusters, select the appropriate cluster to proxy traffic to this resource
Hostname	Required	Hostname for your DocumentDB (single host) resource; must be accessible to a gateway or relay
Port	Required	Port to use when connecting to your DocumentDB (single host) resource; default port value is 27017
Connectivity Mode	Required	Select either Virtual Networking Mode, which lets users connect to the resource with a software-defined, IP-based network; or Loopback Mode, which allows users to connect to the resource using the local loopback adapter in their operating system; this field is shown if Virtual Networking Mode enabled for your organization
IP Address	Optional	If Virtual Networking Mode is the selected connectivity mode, an IP address value in the configured Virtual Networking Mode subnet in the organization network settings; if Loopback Mode is the selected connectivity mode, an IP address value in the configured Loopback IP range in the organization network settings (by default, 127.0.0.1); if not specified, an available IP address in the configured IP address space for the selected connectivity mode will be automatically assigned; this field is shown if Virtual Networking Mode and/or multi-loopback mode is enabled for your organization
Port Override	Optional	If Virtual Networking Mode is the selected connectivity mode, a port value between 1 and 65535 that is not already in use by another resource with the same IP address; if Loopback Mode is the selected connectivity mode, a port value between 1024 to 64999 that is not already in use by another resource with the same IP address; when left empty with Virtual Networking Mode, the system assigns the default port to this resource; when left empty for Loopback Mode, an available port that is not already in use by another resource is assigned; preferred port also can be modified later from the Port Overrides settings
DNS	Optional	If Virtual Networking Mode is the selected connectivity mode, a unique hostname alias for this resource; when set, causes the desktop app to display this resource's human-readable DNS name (for example, k8s.my-organization-name) instead of the bind address that includes IP address and port (for example, 100.64.100.100:5432)
Authentication Database	Required	Name of the DocumentDB authentication database (for example, “admin”).
Secret Store	Optional	Credential store location; defaults to Strong Vault; learn more about Secret Store options
Username	Required	Username to utilize when connecting to this datasource; displays when Secret Store integration is not configured for your organization or when StrongDM serves as the Secret Store type
Password	Required	Password for the user connecting to this datasource; displays when Secret Store integration is not configured for your organization or when StrongDM serves as the Secret Store type
Username (path)	Required	Path to the secret in your Secret Store location (for example, path/to/credential?key=optionalKeyName where key argument is optional); required when using a non-StrongDM Secret Store type
Password (path)	Required	Path to the secret in your Secret Store location (for example, path/to/credential?key=optionalKeyName where key argument is optional); required when using a non-StrongDM Secret Store type
Resource Tags	Optional	Datasource Tags consisting of key-value pairs <KEY>=<VALUE> (for example, env=dev)

Secret Store options

By default, datasource credentials are stored in StrongDM. However, these credentials can also be saved in a secrets management tool.

Non-StrongDM options appear in the Secret Store dropdown if they are created under Network > Secret Stores. When you select another Secret Store type, its unique properties display. For more details, see Configure Secret Store Integrations.

Resource status

After a resource is created, the Admin UI displays that resource as unhealthy until the healthchecks run successfully. When the resource is ready, the Health icon indicates a positive, green status.

When the resource does not display a positive status, click the resource name to go to the Diagnostics tab and check for errors.

Test the Connection

After you have created the DocumentDB datasource, you can use the MongoDB Shell to test the connection to DocumentDB.

1. Run the following command to connect to the instance running on your localhost: mongosh "mongodb://localhost:<PORT>/admin"

   Example: mongosh "mongodb://localhost:37018/admin"

2. Once connected, execute the following command to see the databases: show dbs

When these steps succeed, you’re ready to connect to your resource through StrongDM.
